Abstract

A wireless communication device includes a mobile wireless communication signal creation and reception circuit ( 310 ) coupled to a resonator ( 320 ) capable of sending and/or receiving wireless communication signals. A parasitic element ( 340 ) is coupled to the resonator ( 320 ) in an approximately orthogonal arrangement such that the parasitic element ( 340 ) and the resonator ( 320 ) resonate together to send and/or receive a wireless communication signal. Preferably, the parasitic element ( 340 ) and resonator ( 320 ) are contained within a housing ( 520 ) of a wireless communication device handset ( 500 ) to provide improved communications with a satellite ( 700 ).

Claims (27)

1. An apparatus comprising:

a mobile wireless communication signal creation and reception circuit;

a resonator coupled to the mobile wireless communication signal creation and reception circuit wherein the resonator is capable of radiating electromagnetic energy;

a parasitic element coupled to the resonator in an approximately orthogonal arrangement such that the parasitic element and the resonator resonate together to send and receive a wireless communication signal; and

a ground plane coupled to the resonator;

wherein the resonator and the parasitic element comprise an approximately V-shaped dipole.

2. The apparatus of claim 1 wherein the ground plane coupled to the resonator further comprises a dielectric substrate board and the ground plane is coupled to the parasitic element at approximately an antenna feedpoint for the resonator.

3. The apparatus of claim 2 wherein the dielectric substrate board is integral with the mobile wireless communication signal creation and reception circuit and is contained within a wireless communication handset.

4. The apparatus of claim 1 wherein the ground plane coupled to the resonator further comprises a finite size disposed within a housing enclosing the mobile wireless communication signal creation and reception circuit.

5. The apparatus of claim 1 wherein the resonator coupled to the mobile wireless communication signal creation and reception circuit further comprises an arm extending from and approximately parallel to the ground plane.

6. The apparatus of claim 5 wherein the parasitic element extends approximately adjacent and approximately parallel to the ground plane.

7. The apparatus of claim 6 wherein the parasitic element is printed on a printed circuit board.

8. The apparatus of claim 6 wherein the mobile wireless communication signal creation and reception circuit is contained within a wireless communication handset and the parasitic element further comprises a conductor on a housing of the wireless communication handset.

9. The apparatus of claim 1 wherein the wireless communication signal further comprises a signal sent from a satellite.

10. The apparatus of claim 9 wherein the wireless communication signal further comprises a global positioning system signal.

11. An apparatus comprising:

a mobile station handset including a housing;

a ground plane disposed within the housing;

a main antenna coupled to the ground plane; and

a secondary resonator passively coupled approximately orthogonally to the main antenna, the secondary resonator having a length sufficient such that the secondary resonator and the main antenna resonate together at a frequency for receiving a signal from a satellite;

wherein the main antenna and the secondary resonator comprise an approximately V-shaped dipole.

12. The apparatus of claim 11 wherein the main antenna is further operable to send and receive wireless communications at least one frequency substantially different from the frequency for receiving the signal from the satellite.

13. The apparatus of claim 11 wherein the frequency for receiving the signal from the satellite is that of a global positioning system signal.

14. The apparatus of claim 11 wherein the secondary resonator is parasitically coupled to the main antenna adjacent to a feedpoint for the main antenna.

15. The apparatus of claim 11 wherein the secondary resonator is disposed on any one of:

the housing; or

a printed circuit board disposed within the housing.
